Why Grow Cassava at Home
Cassava is a genuinely tough, rewarding crop for the right climate. It tolerates drought and poor soil better than most root vegetables, and mature roots can be left in the ground for months past maturity, giving you real flexibility on when to harvest. For home gardeners in warm climates, it's a satisfying staple crop that asks for very little fuss once established.

A quick, important note on how it's grown: cassava is propagated from stem cuttings rather than true seed, and that's genuinely for the best. Plants grown from botanical seed are unlikely to grow true to their parent and can revert to bitter, higher-cyanide types — even from a sweet parent plant. Growing from cuttings taken from a proven, cultivated sweet variety is the standard, reliable way home gardeners and commercial growers alike propagate this crop.

What to Know Before Planting Cassava
All Parts Are Toxic Raw — This is essential safety information: cassava contains natural cyanogenic compounds (mainly linamarin) throughout the plant, including the roots and leaves, and is toxic if eaten raw or improperly prepared. Roots must be peeled and thoroughly cooked before eating — boiling, along with traditional processing methods like soaking or sun-drying, significantly reduces cyanide content. Bitter varieties carry meaningfully higher cyanide levels than sweet varieties and require more thorough processing.

Only Grow From Sweet, Cultivated Stock — Stick to planting material sourced from known, cultivated sweet varieties bred specifically for food use. Wild or ornamental variegated forms of Manihot are often bitter and considerably more toxic, and aren't suitable for a home food garden.

Climate Requirements — Cassava needs consistently warm tropical to subtropical conditions, generally USDA zones 9-11, with temperatures reliably above 60°F. It has no frost tolerance whatsoever.

Space Requirements — Cassava plants need real room to develop their root systems properly, generally spaced 3 to 4 feet apart in all directions.

Gardening Insights: Growing Cassava From Stem Cuttings
Sunlight: Full sun is best for strong growth and good root development.

Soil: Cassava adapts to a wide range of soil types, including relatively poor or marginal soil, as long as drainage is reasonable. It isn't a particularly demanding crop once established.

Starting cuttings: Use woody stem sections about 12 inches long, with leaves removed. Plant directly into moist, well-drained soil, either horizontally just below the surface or at a slight angle, and keep consistently moist until the cutting establishes and sprouts.

Timing: Plant during consistently warm weather, once soil temperatures are reliably warm and there's no risk of cool nights slowing establishment.

Care once established: Water regularly while plants are young, tapering off once established, since mature cassava tolerates dry spells well. Prune periodically to keep plants a manageable height, generally around 3 feet, which also supports better root development. Harvest roots once mature, typically 8 to 12 months after planting depending on variety and climate, and always process thoroughly before eating.

Frequently Asked Questions
Should cassava be grown from seed or cuttings?
Stem cuttings, not true seed. Plants grown from botanical seed are unlikely to grow true to type and can revert to bitter, higher-cyanide varieties even from a sweet parent plant. Cuttings taken from a proven sweet variety are the standard, reliable propagation method.

Is cassava safe to eat raw?
No. Cassava contains natural cyanogenic compounds throughout the plant and is toxic if eaten raw. Roots must be peeled and thoroughly cooked, and traditional processing methods like soaking, boiling, or sun-drying further reduce cyanide content before eating.

How long does cassava take to mature?
Cassava roots typically take 8 to 12 months to mature, depending on variety and climate, and can be left in the ground for a period beyond that if not immediately needed.

What climate does cassava need?
Cassava needs consistently warm, frost-free conditions, generally USDA zones 9-11, with temperatures reliably above 60°F. It has no tolerance for frost or cold periods.
